CONVERTIBLE-TYPE DUMP-CAR.

:Specification of Letters Patent.

Patented Oct. 24, 1916.

To all 'Lo/0m t may concern:

Be it known that I, Ancriin CAMPBELL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Convertible-TypeDump-Cars, of which the following is a full, clear, concise, and eXactdescription, reference being had to the accompanying drawings, formingal part of this speciication.

rIhis invention ielates to improvements in convertible type dump oar.

An object of the invention is to provide a car which may be used eitheras a gondola, side dump or center dump-car.

Another object of the invention is to provide a car of the type aboveindicated which is so arranged that it will resist the buffing shocksand has a center sill in addition to load carrying intermediate sills.

The invention furthermore consists in the improvements in the parts anddevices and in the novel combinations of the parts and devices, 'asherein shown, described or claimed.

In the drawing forming a part of this specification, Figure 1 is a sideelevation of substantially half a car showing my iinproveinents embodiedtherein. l Fig. 2 1s a top plan view of the car illustrated in Fig. 1and is broken substantially at the center of the car and Fig. 3 vis anenlarged detail transverse sectional view taken substantially on theline 3-3 of Fig. 2, the left hand portion of Fig. 3 showing the partswhen the car is arranged either for service as a gondolaor for sidedumping and the right hand portion showing the parts positioned when thecar is being utilized as a center dump car.

In said drawing, 10-10 denote the wooden side walls of the car, 11 theend sill, 12-12 the vertical side stakes, 13-13 the side sills which, asshown, are in the form of channels disposed above the floor level of thecar, 14-14 the load carrying intermediate longitudinal sills and 15thegenter sill.

As shown, each intermediate longitudinal sill 14 comprises a verticalplate 16 having angles 17 -17 secured to the top thereof and angles18--18 secured to the bottom. The center sill, as shown, comprises anI-beam reinforced by angles 19`19, said angles also serving anotherpointed out.

As will be understood by those skilled in the art, both the intermediatesills and the center sill may be constructed otherwise than as I haveshown, although I consider the forms illustrated as preferable. Betweeneach intermediate sill and the side stakes are diaphragm plates 20 andbetween each intermediate sill and the center sill are diaphiagin plates21-21, it being understood that said plates are suitably flanged topermit riveting to the sills and side stakes. The end floor of the car,as shown.y is made permanent as indicated by the Hoor boards 22.Intermediate the permanent end Hoor portions of the car, and over whatis commonly designated the hopper section of the car between the trucks,the Hoor of the. car comprises sets of hinged floor doors 23 and sidedumping hinged floor doors 24. The

function as hereinafter floor doors 23 are provided with hinge strapsv25 mounted on hinge pins 26 and the side dumping doors 24 are providedon their inner edges with Corresponding hinge straps 27 mounted on thesame hinge pins 26.

When the car is used for gondola service,

the hinge floor doors 23 have their free or inner edges resting upon thecenter sill 15 and the doors 24 are held up in horizontal position bysuitable door operating mechanism, such for instance, as the chains 28wound over longitudinally extending operating shafts 29 suitably mountedin bearings formed in the side stakes and other bearings 30 located atthe ends thereof. The operating shafts 29 are squared at their endswhereby the same may be operated by a claw bar or other suitable deviceand in order to lock the saine, each shaft is provided with latch wheels31 and latches 32 coperable therewith. For side dumping, the floor doors23 are left in the position shown in the left hand portion of Fig. 3 andthe hinge doors 24 are lowered as indicated by the dotted lines on theleft hand portion of Fig. 3.

When the car is utilized for center dumping, the doors 23 are swung upto the position indicated on the right hand portion of Fig. 3 at 23A,the upper edges of the doors 23 resting against the side walls 10 of thecar. The center dump hinge doors 33 are hinged at their upper edges byhinge straps 34 to hinge butts 35 secured to the center sill lbeneaththe angleirons 19. *'Each door 33 has strengthening angle irons 36 atits ends and said doorsA are operated by means of chains 37 connected'at one end to brackets 38 secured to the doors .33, said chains windingover longitudinally extending operating lshafts 39 mounted beneath theintermediate sills 14. The shafts'39 are suitably mounted in bracketsyandA are squared at their ends and provided with latch wheels andlatches as indicated at 40 whereby the same are operatedand locked inthe usualmanner. Secured to the inner side of each intermediate sill 14,near the bottom thereof, and extending between each pair of diaphragms21, are inclined diverting boards 41, the latter being bolted orotherwise suitably secured to brackets or braces 42 which in turn areriveted to the intermediate sills and angles 18. These diverting boardsserve to divert the material to points between the tracks, when the caris being utilized as a center dump car, it being understood that therails arelocated directly beneath the intermediate sills 14. Each of thecenter dump doors 33 is provided along its upper edge with a flange 43which serves to cover the hinges and in conjunction with they angles 19prevents material from falling between the angles and the doors 33. Asshown in Fig. 2, when the car is vbeing' used as either a side or center'dump car, temporary ends may be formed at the ends of the hoppersection'by boards 44 which are removably held between angles 4:3 45secured to the inner faces loit' the car sides. lVhen the boards 44 arenot being used, they may be stored by placing the same between the ends11 of the car and angles 46-46 (see Fig. 2).

From the preceding description it will be seen that I have provided acar of the convertible-type which is of strong construction, which maybe readily changed from either side to center dumping, or vice versa,and wherein a center sill construction is employed in addition to theintermediate sills which center sill not only absorbs the buiiing shocksin direct line with the draft rigging but is also of value on account ofits vertical strength. l

As will be understood by those skilled in the art, various changes maybe made in the details of construction and arrangement of parts,particularly the various door operating mechanisms and constructions ofthe sills.

rlhe form which I have shown and described I consider the preferable onebut contemplate all changes and modifications coming within the scope ofthe claims appended hereto.

I claim 1. In a car of the character described, the combination with acar body having intermediate sills with hoppers formed therebetween, anda center sill adapted to absorb bufling shocks in direct line with thedraft rigging and having also a vertical strength value, of pivotedfloor doors, some of said doors being adapted to cover said hoppersbetween the intermediate sills and being partly supported by said centersill when acting as iioor members, and others of said floor doors beingadapted to dump to the sides of the car.

2. A car of the character described having side walls and a hoppersection between the trucks, the floor of said car over the hoppersection consisting of sets of hinged doors, one set being adapted toswing downwardly from normal horizontal position to thereby dump theload to the sides and the other set being adapted to be swung upwardlyfrom normal position to an outwardly and upwardly inclined position,said car having also center dump doors located below the ioor level ofthe car and hinged along their inner upper longitudinal edges.

3. A ear of the character described having side, deep intermediate sillsand diaphragms, said intermediate sills having diverting boards alongtheir lower edges, said car having also hinged center dump doors locatedentirely below the ear floor level, hinged side dumping floor doorsextending between the vintermediate and the side sills, and movablefloor sections arranged to either cover the hopper spaces between theintermediate sills or to form inclined hopper bottoms.
